The short answer is yes. I found a supplier in Canada, Cherry Forest Products, which distributes to both Canada and the United States and their thermally modified wood decking and siding products are FSC Certified and they provided me proof of their certification by showing me their current certificate which is issued by the Forest Stewardship Council (FSC).
From what I understand FSC and LEED (Leadership in Energy and Environmental Design) is apparently a green building rating system aimed to assure environmentally sustainable design and construction by rating buildings on their ability to meet certain criteria in six categories.
Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials & Resources, Indoor Environmental Quality and Innovation in Design.
The LEED rating depends on the number of points a particular building earns either silver, gold or platinum.
I did not realize that residential construction consumes almost half of North America’s softwood. In conversations with local architects, builders and consumers there seems to be a growing commitment to ensure that our North American forests remain sustainable.
Thermally Modified Wood is a great building material; versatile, requires little (embodied) energy to produce, durable, and comes from renewable and well managed forests here in North America which eliminates the need to purchase foreign tropical species such as Ipe which have become more scrutinized due to illegal harvesting
